问题描述
我想让它有点像生命系统,这样如果它与敌人碰撞 3 次就会退出
pygame.init()
screen_width = 800
screen_height = 600
window = pygame.display.set_mode((screen_width,screen_height))
pygame.display.set_caption('Test')
time = pygame.time.Clock()
bg_color1 = (135,142,142) # MAIN BG COLOR
bg_color2 = (255,0) # red
bg_color3 = (255,255,0) # yellow
UFO = pygame.image.load('ufo.png')
bg_pic = pygame.image.load('Letsgo.jpg')
clock = pygame.time.Clock()
playerImg = pygame.image.load('enemy.png')
playerX = random.randrange(0,screen_width)
playerY = -50
playerX_change = 0
player_speed = 5
def player(x,y):
window.blit(playerImg,(playerX,playerY))
crashed = False
rect = UFO.get_rect()
obstacle = pygame.Rect(400,200,80,80)
menu = True
playerY = playerY + player_speed
if playerY > screen_height:
playerX = random.randrange(0,screen_width)
playerY = -25
def ufo(x,y):
window.blit(UFO,(x,y))
while menu:
for event in pygame.event.get():
if event.type == pygame.QUIT:
quit()
elif event.type == pygame.MOUSEBUTTONDOWN:
if event.button == 1:
menu = False
window.fill((0,0))
time.tick(30)
window.blit(bg_pic,(0,0))
pygame.display.update()
x = (screen_width * 0.45)
y = (screen_height * 0.8)
x_change = 0
car_speed = 0
y_change = 0
while not crashed:
x += x_change
if x < 0:
x = 0
elif x > screen_width - UFO.get_width():
x = screen_width - UFO.get_width()
y += y_change
if y < 0:
y = 0
elif y > screen_height - UFO.get_height():
y = screen_height - UFO.get_height()
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
############SIDE TO SIDE################
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x_change = -5
elif event.key == pygame.K_RIGHT:
x_change = 5
if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
x_change = 0
###########UP AND DOWN#################
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
y_change = -5
elif event.key == pygame.K_DOWN:
y_change = 5
if event.type == pygame.KEYUP:
if event.key == pygame.K_UP or event.key == pygame.K_DOWN:
y_change = 0
if playerY > screen_height:
playerX = random.randrange(0,screen_width)
playerY = 0
playerY += 10
##
window.fill(bg_color1)
ufo(x,y)
player(playerX,playerY)
pygame.display.update()
clock.tick(100)
pygame.quit()
quit()
我正在考虑使用collide.rect但无法弄清楚任何帮助表示赞赏 我想让“playerImg”成为敌人...................................... .....................................................
解决方法
创建一个变量来存储生命的数量。使用 pygme.Rect
方法创建玩家和 UFO 的 get_rect
对象。通过关键字参数设置矩形的位置。使用 colliderect
测试碰撞并在检测到碰撞时减少生命次数并创建新的随机起始位置:
lives = 3
while not crashed:
# [...]
player_rect = playerImg.get_rect(topleft = (playerX,playerY))
ufo_rect = UFO.get_rect(topleft = (x,y))
if player_rect.colliderect(ufo_rect):
lives -= 1
print(lives)
playerX = random.randrange(0,screen_width)
playerY = 0
if lives == 0:
crashed = True
# [...]
